Design scheme of battery pack for mini ev：

1） protection circuit board （PCM）：Mainly design against protection circuit board for rechargeable high capacity battery pack. Because of the chemical characteristics of lithium battery, in order to avoid burning, explosion etc. dangerous situation, must provide over charge, over discharge, short circuit, over current & over heat etc. protection function.

2）protection IC（Protection IC）：Main protection function chip in design scheme, carry on-line constantly monitor on over charge, over discharge, over current, short circuit etc. function of battery cell. Ensure batter cell work within the scope of safety, stability, high efficiency.

3） over current protection chip（PTC）：Mainly design against secondary protection function. PTC can recover thermal fuse with dual function: over current protection & auto recovery. PTC inside battery cell can prevent the cell occurs high temperature discharge and un-safe large current.

4）MOSFET chip：MOSFET chip, on on-off action in protection circuit

5）Packing of battery pack：plastic film

Application Fields:

home energy storage, mini ev, ebike, golf cart etc.
